Spright Deck #761979 — Yu-Gi-Oh! Master Duel

Deck — Deck Power Evaluation

Final Contextual Deck Power: 35/100 (±6 · Confidence: Medium)

• Primary strategy: Midrange
• Secondary strategies: Tempo, Toolbox
• Format: master-duel

Legality

Main 40 / Extra 15 / Side 0 — status: Illegal. 1 violation(s).

Identity & game plan

• Win condition: Level/Rank/Link 2 Spright board converted into Link/Xyz pressure (Spright Elf, Spright Sprind, Gigantic Spright); Nimble and Frog tempo bodies feeding Spright Starter / Spright Blue search and summon chains
• Turn 1 (going first): Open Spright Starter or a Level 2 starter, Special Summon a Level 2 Spright into Spright Jet / Spright Blue searches, then link out to Spright Elf or Sprind while holding Ash Blossom and Infinite Impermanence
• Turn 2 (going second): Use Ash Blossom, Infinite Impermanence and Spright Carrot / Red negations to stop the opponent's first board, then rebuild with Level 2 summons
• Recovery: Spright Jet and Spright Blue each search a Spright from the Deck; Nimble Beaver and Nimble Angler recur Level 3 or lower Nimble monsters from the GY
• After siding: No side deck is run (side_count 0), so no post-side plan exists in this list

Why it scores here

This list is illegal in Master Duel because it runs one copy of Called by the Grave, which is Forbidden there, so the score is capped and reported as a structural-only, theoretical read. Within that read, the Spright core (24 archetype-core copies, about a 99% chance of at least one core card in a 5-card opening hand) gives the deck reliable early access to a Level 2 engine, and the interaction suite (Ash Blossom, Infinite Impermanence, Spright Carrot and Red negations) gives it real end-board control. The weaknesses are a missing side deck, a large off-archetype share (about 62% of main-deck copies are not exact Spright names), and no recorded boards to confirm a median or ceiling output. Each dimension was scored on the whole system, not by averaging the card scores, and the archetype's popularity in the usage statistics was not counted as power.

Dimension scores

How the score was computed

Strategy profile: Midrange. Structural ≈ 47.5, Going First ≈ 47, Going Second ≈ 41, Meta = provisional, Tournament Reliability ≈ 45. Modifiers: banlist_exposure (-12). Final formula: 0.80*Structural + 0.20*TournamentReliability (Meta provisional) + ContextModifiers; illegal-list cap applied (theoretical, structural-only)

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.34 · key two-card combo ≈ — · full-brick estimate ≈ — (all Inferred)
• Combo output: best PowerIndex —, median —, board-per-starter —
• Turn order: 0 going-first lines vs 0 going-second lines

Strengths

• Level 2 Spright engine is densely packed with searchers and summons
• Ash Blossom, Infinite Impermanence and Carrot/Red negations give layered interaction
• Archetype-core group is almost always present in an opening hand

Weaknesses

• Called by the Grave is Forbidden in master-duel, so the list is illegal
• No side deck
• 34 of 40 main copies are off-archetype or generic, which weakens engine coherence
• No recorded combos to confirm median or ceiling output

Critical choke points

• Spright Starter and a Level 2 starter are needed to begin the engine
• Single-copy Extra Deck cards (Divine Arsenal, Downerd Magician, Cat Shark) are one-of access points
• Lack of a side deck leaves no answer to a bad matchup

Recommended changes

Evidence & confidence

• Verified: Called by the Grave is Forbidden in master-duel and run at 1 copy (illegal); Main 40 and Extra 15 match master-duel size rules; Side 0 is within 0–15; Copy histogram and archetype purity from composition
• Observed: Archetype-core usage statistics (24 core copies; 11 of 22 core cards present)
• Inferred: Opening-hand starter probabilities; Interaction density from card-text tags; Going-first and going-second splits from the card-text read; Dimension scores D1–D11 and D14
• Provisional: Meta Power is null; D13 format fit is provisional without a dated metagame sample
• Data gaps: no combos supplied — combo floor/median/ceiling is text-only inference no tournament link — archetype meta-share and per-pilot match record absent no win-rate telemetry exists in YGOVN (going-first/second, matchup, game-level, brick/starter/OTK rates) — those signals are Inferred or Unknown Meta Power is Provisional unless a dated metagame sample is supplied no side deck present, so D12 cannot be measured from a post-side list
